Prostate cancer in American Indians, New Mexico, 1969 to 1994.
OBJECTIVE
Prostate cancer is the most frequently diagnosed cancer as well as the leading cause of cancer death among American Indian men.


METHODS
To describe further the occurrence of prostate cancer among American Indian men, we examined population based incidence, treatment, survival and mortality data for American Indians in New Mexico during the 25-year period 1969 to 1994.


RESULTS
Although American Indian men have a lower risk of prostate cancer than nonHispanic white men, the incidence and mortality rates are rising for American Indians, and mortality rates are now equal to those for nonHispanic white men. During the 25-year period age adjusted incidence rates for American Indians increased from 42.2/100,000 (95% confidence interval 27.1 to 57.3) to 64.6/100,000 (95% confidence interval 46.2 to 83.0). The burden of prostate cancer among American Indian men compared with nonHispanic white men was reflected in disproportionately high mortality rates in relation to incidence rates. The mortality rates were high because American Indian cases were more advanced at diagnosis, 23.3% of prostate cancers were diagnosed after distant spread had occurred compared with 11.6% for nonHispanic white men and the 5-year relative survival rate was poorer (57.1% compared with 77.6% for nonHispanic white men).


CONCLUSIONS
Effective and culturally sensitive cancer control efforts for prostate cancer in American Indian communities are urgently needed.
